That being said, I always thought their Flash app was amazingly slick and polished, so it's a tough act to follow I suppose.
EDIT: Plus if they are going to go this far with HTML5 it'd be awesome if they could cut the Flash cord entirely. Not sure if that's technically possible though.
On Ubuntu 10.04 x64 Flash is pretty stable for me, except when I've got 40 Firefox tabs open (yes I'm seeing a therapist about that) and then try to run some Flash app that's more complex than a mere Youtube video. No more popping htop to manually kill nspluginwrapper that's in some kind of infinite loop ftw.
Besides that, it's awesome, even better than before.
Hat-tip to Gruber for the idea http://daringfireball.net/2010/11/flash_free_and_cheating_wi....
